### Residual Entropy?

Posted:

**Tue Feb 05, 2019 5:25 pm**One of the examples in the 7th edition text book in chapter 4G gives an example of calculating entropy and they get 11.52 which they say is "reasonably close" to the given S=10.1, my question is what qualifies as being reasonably close for the two entropy values to determine if the molecules are randomly aligned or not? How big of a difference would there have to be between two values for it not to be considered 'reasonably close'? Thanks!
